Re: Drippy AC

["Jim Reeve" <ultra@xxxx>]

The casing should already have some insulation on it. The entire flat 
bottom portion and the lower side walls on my unit have a thin piece 
of foam covering most of each side. This seems to help with most of 
the condensation. Also, when the AC is on in a closed car, the temp 
with drop along with the humidity, so interior condensation will be at 
a minimum. However I too had a clogged drain tube ealier this year. 
But many of the leaks from it appeard to be condensation, so I was 
stumped for a little bit. When I figered out it was glogged up it 
actually took quite a while to get it cleared out. After an 
unsuscessfull attempt to "suck" the blockage out, I blew it back in. 
It drained a crapload of water, but clogged back up again the next 
day. Here is where it is nice to have skinny little arms. I removed 
the blower fan and the speed resistors, then reached my hand into the 
evaporator casing. I pulled out a few handloads of crud. After 
another round of sucking and blowing the drain tube, it seems to have 
cleared up good. No more wet carpets for me. But with all this heat 
I just wish my AC could make up its mind weather it wants to work 
incredibly good, or just mediocre.
